Driving assistance apparatus for assistance with driving along narrow roadways

摘要

A driving assistance apparatus for a motor vehicle for assistance with driving along narrow roadways is provided. The apparatus includes a data acquisition unit for acquiring route data while driving on a route obtained from wheel and steering angle sensors, a trajectory storage unit for recording the route data, and a triggering unit for triggering the vehicle based on the route data. The apparatus is coupled to a satellite navigation receiver for determining boundary value position data at the time of commencement and/or end of the route. A storage unit stores the boundary value position data for the route data. An approach checking unit checks whether the vehicle is approaching the commencement or end of the route based on the boundary value position data and generates a position approach signal if the motor vehicle is approaching the commencement or end of the route.

主权项

1. A driving assistance apparatus for a motor vehicle for assistance with driving along narrow roadways, the driving assistance apparatus comprising:
a data acquisition unit configured for acquiring route data while driving on a route to be obtained from wheel and steering angle sensors; a trajectory storage unit configured for recording the route data of the data acquisition unit, wherein the driving assistance apparatus is coupled to a satellite navigation receiver for determining boundary value position data at a time of commencement and/or end of the route and the trajectory storage unit is configured for storing the boundary value position data for the route data; a triggering unit configured for triggering the motor vehicle on a basis of the route data recorded by the trajectory storage unit, for driving along the route in the same or reverse direction; and an approach checking unit configured to check whether the motor vehicle is approaching a commencement or end of the route based on the boundary value position data and to generate a position approach signal if the motor vehicle is approaching the commencement or end of the route, and wherein the position approach signal is supplied to a driver communication unit, which is configured to provide a driver of the motor vehicle with an option for activating an automatic driving of a corresponding route and optionally activates the triggering unit for autonomous driving of the route by the motor vehicle, and wherein, when selecting a route to be driven, the driver communication unit selects accessibility of a door and/or a trunk of the motor vehicle.
